A Tri-Bahtinov mask operates under the same principle as the Bahtinov mask for focusing and adds the ability to collimate scopes with collimatable optics.  
The design is based on Cytan's idea, documented on his Github site here, and the sketch was made using Satoru Takagi's Mask Generator.
The mask has a raised center for an easy grip and comes in three sections that snap fit together and can be taken apart for easier storage (C5 is one piece, 14" and larger are 6 sections). 

If you don't see your scope listed below Buckeye will be happy to design a mask to meet your needs.
